KMD-15C to 50C［Application］
These demagnetizers produce an alternating magnetic ﬁeld on the surface by use of an AC power source, through which workpieces are passed to remove
the magnetism remaining on their surface.
［Features］●Thick workpieces can be demagnetized eﬀectively by moving both the face and the back over the demagnetizer.
●These demagnetizers have good heat radiation and can withstand continuous power-on condition.
●These demagnetizers are very powerful and can demagnetize steel materials that have properties similar to magnetic steel and have large magnetism
holding power such as high-speed steel, bearing steel, nickel-chrome steel, spring steel, die steel, etc. that are usually diﬃcult to demagnetize. (KMD-2A,

MAGNETIC TOOLS & EQUIPMENT
FOR WELDING OPERATION●The strong magnetic ﬁeld produced by the demagnetizer may cause the CRT ofcomputer and NC units to ﬂicker. It will not adversely affect the operation ofthese equipment, but if it causes a recognition problem, such measures must be
taken as keeping the CRT away from the demagnetizer or installing a magnetic
shield on the CRT side.
●The demagnetizers have large inductance and low power factor. Take inﬂuenceon the power source into consideration.
●The standard models cannot be used on 220 VAC, 50 Hz. For such application,please contact us.
●The demagnetization effect varies largely depending the conditions ofworkpieces. In particular, some materials are very difficult to demagnetize
depending on the condition of heat treatment.

●Be sure to observe the working rate.
●Move a workpiece over the demagnetizing surface slowly in the direction of A-B.
Note that the workpiece must be moved more than 20 cm away from the end of
the demagnetizer to be demagnetized eﬀectively. (Table type)●When the tunnel type demagnetizer is used, pass the workpiece through the tunnel.
●The recommended time for passing the workpiece is about 5 seconds.
(Recommended speed: 3 to 5 m/min)●Some demagnetizers may be heated to very high temperature due toelectromagnetic induction action. Exercise caution when handling them.
●If there is any other metal near the demagnetizer, it may also be heated. Keepsuch metal at least 5 cm away from the demagnetizing surface, and approx. 30
cm or more away when the tunnel type demagnetizer is used. However, if suchseparation is not possible, use plastics or nonmagnetic materials such as
SUS304 for peripheral machinery.

［Features］
Stronger magnetic ﬁeld produced ●Demagnetization is carried out by varying (sweeping) a frequency
lower than commercial frequencies from a lower point to a higher
than standard table type!

point. This design has improved the demagnetizing performance
without increasing the amount of electricity to use.
●The demagnetizing section is of the same dimensions as theconventional table type demagnetizer (KMD-C). With the same output
current (AC eﬀective value) as the conventional model, the residual
magnetism in workpieces (SKH material) can be reduced to one third.
●Workpieces are demagnetized by passing them over the demagnetizing
surface at a constant speed, as with the conventional model.
●Continuous power on specification, but heat generated in the
demagnetizing part is less than the conventional model.
●A demagnetizing output variable resistor is provided on the electricalunit that can vary the output current (AC eﬀective value) in a range of
100% and 70%. This feature achieves demagnetization of low-carbon
steel like S45C by less power (70%) than the conventional model.

DEM ADJ.

［Application］
Used to eliminate residual magnetism in magnetized workpieces
and tools. Pressing the demagnetizing button can complete
demagnetization within a certain time without moving
workpieces.
［Features］●A magnetomotive force greater than the AC demagnetizer has
been set, which works well on hard workpieces such as
bearing steel and cutter steel that are diﬃcult to demagnetizewith conventional demagnetizers.
●Since workpieces are demagnetized while they are kept
stationary on the demagnetizer, it is not necessary to move
workpieces, press die materials, SK materials, etc. as whenusing an AC demagnetizer. Thus, this model is suitable fordemagnetization of large workpieces (e.g. molds) that are
diﬃcult to move.
●Since demagnetization is carried out according to theattenuation pattern programmed in the control unit, electricity
needs to be applied only during demagnetization, thus saving
electricity.
●The demagnetizer itself and the control unit are installed
separately. Thus, they can be installed in an easy-to-operate
place.

Model KMDH-P PINPOINT TYPE DEMAGNETIZER［Application］

NonwatertightAn alternating ﬁeld is produced at the tip and bottom by an AC power source, which is brought
into contact with a workpiece and then moved away. Then the magnetic flux density on thesurface is reduced locally. This demagnetizer works eﬀectively in demagnetizing molds and largematerials partially.

●Since this demagnetizer produces a strong magnetic field at the tip, it can effectively
demagnetize places that are diﬃcult to demagnetize with a conventional table type or handy
type demagnetizer.
●The magnetizing eﬀect is powerful, but the attracting force is not strong. Thus, the tip partcan be brought into contact with a small area for easy handling.
●A thermo label is attached to the tip part, which warns a temperature rise due to frequent,repeated use. When the thermo label appears, stop using the demagnetizer until it goes out.

127［Application］
Recommended where magnetism on the surface of metallic workpieces in general needs to be
reduced in a limited area or locally.
This is useful to completely eliminate weak magnetism that remains locally in jigs and workpieces
after they have been demagnetized by a large demagnetizer. It is also useful for demagnetizing
cutters of machines and punches and guide pins of press dies while they are mounted.
［Features］●Compact and powerful as a rare earth magnet having strong magnetic force is used at the endof the rotary magnetic ﬁeld.
●A re-chargeable battery is used as a power source of the motor. No need to replace the battery.
Power can also be supplied with the included AC adapter if the battery has reached its life.
●Simple construction and simple appearance.
●An environment friendly nickel hydrogen battery is used.

Suitable for demagnetizing workpieces such as bearings that are diﬃcult todemagnetize with conventional demagnetizers.
［Features］●High voltage charged to a large capacitor in the control unit is discharged
to the demagnetizing coil to momentarily demagnetize workpieces by useof LCR resonance and strong magnetic ﬁeld.
●The time required from charging to discharging is only about 10 seconds.
●Workpieces on the conveyor can be demagnetized. (However, in order todemagnetize workpieces, it is necessary to keep them stopped inside thecoil as with the stationary type.)●As the capacity has been increased, coil design according to applications
is possible. (KRMDC-25020)
